D4E-2D20N

Snap Action, Limit Switches are widely used in a wide range of applications and are considered as one of the most reliable and durable switches in the market. The D4E-2D20N is a popular switch among these switches. In this article, we will discuss the application field and working principle of the D4E-2D20N. The general application field of the D4E-2D20N is in automation, control and safety systems, especially in harsh and hazardous environments. Its sturdy and dustproof structure makes it suitable for use in various industries, such as mining, oil and gas, and energy production. The D4E-2D20N is designed with a snap action mechanism. This mechanism provides a precise and repeatable switching point, regardless of frequent and extreme force changes. It is also designed to be reliable and durable, with a long lifetime of more than 5 million switching cycles. When the actuator is pressed, the internal contacts are opened or closed depending on the direction of the force. This is accomplished by a snap action mechanism which includes a movable armature and a plunger. The plunger is spring-loaded and the armature is connected to the plunger through a toggle joint. When the actuator is pressed, the toggle joint flexes and the plunger is pushed further into the switch body. When the force is released, the plunger is returned to its original position by the spring and the contacts are closed again. The D4E-2D20N also includes a voltage fuse which helps to protect the switch from accidental damage or overvoltage. The fuse has a normally open contact, so that when the voltage goes above a certain level, the fuse will break the contact and disconnect the power from the switch. In addition to the application field and working principle of the D4E-2D20N, there are also other features which make it a great choice for applications where reliability and safety are essential. Its UL and CSA approval allows for it to be used in various applications and the various available ratings ensure that the switch can be used for a wide range of load applications.In conclusion, the D4E-2D20N is a reliable, durable and safe snap action limit switch which is suitable for a range of applications. It has a snap action mechanism which provides precise, repeatable switching and a voltage fuse for protection against accidental damage or overvoltage. Its UL and CSA approval and various available ratings make it a great choice for applications in automation, control and safety systems.
